Day 7

Posted by Chris Lambert

This cold from Canada has had some staying power eh?  In Boston, we slid below the freezing mark late in the evening last Sunday, and haven't come back above it since.  In fact, as temps fail to crack the 32 degree mark again today, we'll mark the 7th day in a row of sub-freezing weather.  

Tomorrow may be the eighth, but it'll be close as a warm front slowly increases our temps in the late afternoon and evening.  In addition, that warm front also triggers a batch of light to moderate snow to break out.  Start time on the snow is between 2-5PM, with the earlier arrival in that range outside 495.  That snow will be just in time for the evening commute, and certainly has the potential to slow things down.

Don't expect a ton of snow, but a general 1-3" falls through the evening. Southern Bristol, southern Plymouth and the Cape/Islands will be at the lower end of the snow range, if not under it, thanks to warming temps changing snow over to sleet and drizzle fairly quick. The highest totals show up in northern Mass and Southern NH.  In the city of Boston, 1-2" seems to be a good fit for a range.

The snow changes to sleet and freezing drizzle late in the evening for the rest of us, creating an icy glaze on top of the fresh inch or two of snow (close to the coast, snow goes to plain ole drizzle).  As warm air finally wins the battle, that freezing drizzle turns to plain drizzle by the AM commute on Tuesday.

Tuesday is kind of a blah day.  Nothing special, lots of clouds, temps in the upper 30s.

Wednesday will be windy and warmer, isolated passing shower, temps in the mid 50s. Perhaps even near 60 in some sun breaks out?  Steadier rain works in at night, before colder air ends the week.

Enjoy the rest of the weekend!

Although my forecast was busted today, there was one good thing that came out of it.

Stability.

That gray overcast that hung over the eastern half of the Commonwealth provided a stablizing influence to our atmosphere. The cool air blowing in from the ocean kept the temperatures in the upper 50s and low 60s all the way back to Metrowest. While that makes for lousy short-and-t-shirt weather, it is poison to thunderstorms.

Wild & Wacky

Wild temperatures yesterday---from the 80s down into the low 60s in just an hour AND some heavy duty thunderstorms. The reason was a cool front that dropped in from Maine. That front is in western New England this morning and it's a chameleon as it will become a warm front and try to warm things back up during the day.

What a day! Breakneck temperature swings, thunder, tornadoes in Western Mass....and we're still in late May!

More Warmth

You have another warm & humid day with many towns repeating yesterday's weather. That means we start with clouds & fog for a bit before hazy sun gets going. That hazy sunshine will boost temps up into the low 80s by early to mid afternoon across much of the region. At the same time a cool front will begin dropping out of Maine (backdoor front) which will quickly send temps from the 70s/80s down into the 50s/60s by late afternoon & evening. Also, when this front rams into the warmth & humidity it will spark a few showers & thunderstorms during the afternoon.
